The plan was a failure when Anakin Skywalker, Padmé Amidala, and Jar Jar Binks discovered that Lyonie was under the influence of the necklace. They then confronted Rish, this led to him stabbing Lyonie, buying him time to escape Otoh Gunga for the surface, where the invasion forces awaited and were to meet with Separatist forces. Attempting to take control of the Gungan Grand Army by spreading misinformation regarding Lyonie's apparent death, Loo failed when Binks, disguised as Lyonie, arrived and deemed Rish Loo to be a traitor. Once more escaping aboard a speeder, he eluded the pursuing Skywalker, while simultaneously leading him into a trap.

Rish Loo's death at the hand of Count Dooku.

Loo eventually arrived at his secret lair to meet with CountDooku, but the Sith Lord immediately killed him for his incompetence, before turning his attentions to Anakin, who'd followed Loo all the way to the lair.
